Abstract: A polarizing beam splitter and a preparation method and use thereof are provided. The polarizing beam splitter includes a diamond substrate, a broadband anti-reflection coating and a first metallized layer located on one side surface of the diamond substrate, a polarizing beam splitting coating located on another side surface of the diamond substrate, and a second metallized layer located on a side of the diamond substrate, where the first metallized layer is located on an edge of the one side surface of the diamond substrate. Diamond is adopted as the substrate material of the polarizing beam splitter. The diamond substrate can quickly conduct heat generated by laser irradiation on the layer and the substrate, thereby mitigating damage to the polarizing beam splitter caused by local temperature rise. The metallization treatment on the edge of the polarizing beam splitter providing a high-reliability and low-leakage vacuum sealing solution.

Abstract: A solar dark green glass and a vehicle are provided. The solar dark green glass includes a glass basic component and a glass tinted component. The solar dark green glass includes a glass basic component and a mass tinted component. The glass tinted component includes, as percentages by weight, 0.8%-2.0% total iron expressed as Fe2O3, 0.01%-0.6% TiO2, 0.001%-2.0% CeO2, 5 ppm-150 ppm Cr2O3, 15 ppm-60 ppm Zro2, 2 ppm-1000 ppm CuO, 5 ppm-50 ppm SrO, 80 ppm-200 ppm BaO, and 5 ppm-120 ppm Co2O3. A content of total iron expressed as Fe2O3 and a content of TiO2 total 1.0%-2.0%, and the content of TiO2 and a content of CeO2 total 0.2%-2.1%. The solar dark green glass manufactured has a thickness of 1.6 mm-2.1 mm, and solar direct transmittance less than or equal to 65%, infrared transmittance less than or equal to 45%, and ultraviolet transmittance less than or equal to 35%.
